Phoxopteris nubeculana (Clem.). In the perfect state, this insect is a small moth belongingto the Tortricidse, or Leaf-rollers. It passes the winter inthe larval condition in rolled-up apple-leaves which lie onthe ground. Early in April the larvae change to chrysalids,and about ten days afterwards the moths begin to appear,and continue to issue for several weeks. The moth is white, with brown markings, as shown in , at c. The eggs are laid in June, and the larva is found Fig. throughout the summer and autumn on apple-leaves. Itfolds the leaves together, as shown at b in the figure, makingthe edges meet, so that the whole leaf forms a hollow case,within which it lives and feeds on the softer tissues. Thelarva is of a yellowish-green color, with a yellow head, and 100 INSECTS INJURIOUS TO THE APPLE. with II horny sliield on the next segment, a little darker, witha black dot on each side. On ejich of the remaining segmentsthere are a number of pale, shining, raised dots, from everyone of which arises a single hair. On the approach of winterthe larva lines its chamber with silk, and falls with the leafto the ground, where it remains unchanged until early thefollowing spring, when it becomes a yellowish-brown chrys-alis. As the time approaches for the escape of the moth, thechrysalis wriggles its way through the partly-decayed leaf-case at the back, and protrudes as shown at 6 in the figure,soon after which the moth escapes.
